Contact name turns Red then Blue when sending an iMessage
Greetings, I have a iPhone 13Pro Max, 256GB. Recently I sent a video from IG to save and review later.
I received an error message indicating the message could not be sent, I noticed there was another
contact included on the message contacts "p{null}. I deleted the message and after that whenever I send a message to myself the contact turns Red then Blue, which never did prior to this. Based on my experience typically if the recipient has an iPhone the contact name is Blue and if an Android phone or the message is sent as a text message the contact name is Green. I used an iPad to send a message to myself and the contact name stays Blue. Please advise what can I do to determine if my phone has been hacked. Thank you for your time and look forward to hearing from you and resolving this issue. Thanks
iPhone 13 Pro Max, iOS 18
